A Manhattan psychiatrist has fled to his native Turkey after drugging, raping and sodomizing two 21-year-old female Scandinavian tourists in his hospital-subsidized apartment, prosecutors charged yesterday.

Cops meanwhile have found “a shelf’s worth” of incriminating video tapes in the doctor’s West 59th Street apartment – housing provided through his psychiatry residency at St. Luke’s-Roosevelt Hospital.

The tapes appear to show the 29-year-old shrink, Dr. Selim Can Alkoc, raping several other apparently drugged-out women in the apartment, a law-enforcement source said.

“Some, not all, of the women on the tapes appear to be physically helpless,” said the source. “They’re clearly out of it – not quite unconscious, but not alert either, and not really awake.

“They can’t even protest,” the source said.

Alkoc fled the United States while lab tests were still confirming that the Scandinavian women indeed had ingested knockout drugs – and before Manhattan prosecutors could charge him in the May 23 attack, sources said.

But before fleeing, Alkoc embroiled a hospital colleague in the scandal, say prosecutors with Manhattan’s Sex Crimes Unit, led by Assistant District Attorney Linda Fairstein.

The colleague, Dr. Turker Sengul, 28 – a third-year anesthesiology resident who, like Alkoc, worked at St. Luke’s on a Turkish visa – was ordered held without bail after his arraignment on evidence-tampering charges yesterday.

Alkoc allegedly asked Sengul to destroy the videotapes, which had been stashed under Alkoc’s bed and inside his vacuum cleaner. But Sengul decided to return the tapes to the apartment, the criminal complaint charged.

The sordid tale began when Alkoc, who hails from a prominent and wealthy Turkish family, met the two Scandinavian tourists when all three were traveling in Canada.

The women visited him in late May, only to be rendered senseless a few days into their visit when Alkoc allegedly slipped a drug into their drinks.

When the pair came to their senses and realized, by their bruises, that they had been raped and sodomized, they went to the nearest hospital – St. Luke’s.

A hospital spokesman said both doctors have been suspended, and that the hospital is working closely with prosecutors.

Alkoc faces up to 25 years prison on first-degree rape and sodomy charges. Sengul faces up to four years in prison for allegedly hindering the prosecution and tampering with evidence.

Alkoc’s lawyer, Brian Perskin, insists his client has merely moved back to his homeland.

The rape charges are unfounded, Perskin said, and the confiscated videos “only show him having sex with other women. That’s not against the law.”
